Product details
Overview
TPS25832AQWRHBRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive USB Type-C® and BC1.2 charging port controller with integrated 36-V input, 5.1-V/3.5-A synchronous buck regulator and cable droop compensation. It delivers ±1% VBUS accuracy, supports USB data pass-through via high-bandwidth DP/DM switches, and implements CC logic, VCONN sourcing, and polarity detection for automotive infotainment and USB media hubs.
For engineers reviewing the TPS25832AQWRHBRQ1 datasheet, TPS25832AQWRHBRQ1 pinout, TPS25832AQWRHBRQ1 application, or TPS25832AQWRHBRQ1 equivalent, key selection considerations include its 32-pin VQFN wettable flank package, absence of DP/DM/CC short-to-VBAT protection (vs. TPS25830A-Q1), MFI overcurrent compliance, client-mode firmware update capability, and programmable cable compensation up to 1.5 V.
Technical Context
The TPS25832AQWRHBRQ1 integrates a current-mode-controlled synchronous buck regulator with internal compensation, adjustable switching frequency (300 kHz–2.2 MHz), and FPWM with spread-spectrum dithering. Its USB subsystem includes full Type-C rev 1.3 CC logic, BC1.2 DCP/SDP mode support, and high-bandwidth analog switches (RDS(ON) = 3.4–6.3 Ω) on DP/DM paths.
It features dual current-limit architecture-programmable average buck current limit (via ILIMIT resistor) and optional external NMOS-based limiting-and provides cable droop compensation by linearly increasing VBUS output voltage with load current to maintain constant voltage at the connected device. Unlike TPS25830A-Q1, it omits short-to-battery protection on CC1/CC2, DP_IN, and DM_IN pins.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-C automotive port controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS25830A-Q1 | Includes DP_IN/DM_IN/CC1/CC2 short-to-VBAT protection (up to 18 V); same package and pinout. | Required where data-line short-to-battery fault tolerance is mandated (e.g., exposed connector designs). | Select TPS25830A-Q1 when short-to-battery protection on USB data and CC lines is required; otherwise TPS25832AQWRHBRQ1 offers identical core functionality at lower cost. |
| TPS65987D | Supports USB Power Delivery (PD) 3.0, programmable PDOs, and higher power (up to 100 W); larger 40-pin QFN package. | Used in high-power USB-C applications requiring variable voltage (9/15/20 V) and bidirectional power negotiation. | Choose TPS65987D only if USB PD protocol compliance and >5 V output are needed; TPS25832AQWRHBRQ1 is optimized for fixed 5.1-V, 3.5-A automotive charging. |
Compared with TPS25830A-Q1, TPS25832AQWRHBRQ1 removes short-to-VBAT protection on CC/DP/DM but retains identical buck performance, USB-C/BC1.2 compliance, and cable compensation-making it ideal for cost-sensitive, non-exposed-port automotive charging. Versus TPS65987D, it trades PD protocol flexibility for smaller footprint, lower quiescent current, and simplified firmware.

FAQ
What is the maximum input voltage supported by the TPS25832AQWRHBRQ1?
The TPS25832AQWRHBRQ1 supports an absolute maximum input voltage of 40 V on the IN pin, with recommended operating range from 4.5 V to 36 V. This accommodates automotive battery transients including cold-crank (down to ~6 V) and load-dump events (up to 36 V), ensuring robust operation across vehicle electrical conditions. The device's internal protection circuitry clamps beyond-rated voltages to prevent damage.
Does the TPS25832AQWRHBRQ1 support USB Power Delivery (PD) protocol negotiation?
No, the TPS25832AQWRHBRQ1 does not support USB Power Delivery (PD) protocol negotiation. It implements USB Type-C rev 1.3 physical layer functions-including CC logic, VCONN sourcing, and polarity detection-and BC1.2 DCP/SDP signatures, but lacks the PD controller, BMC transceiver, and programmable PDO engine required for variable-voltage negotiation. For PD-compliant designs, consider TI's TPS65987D or TPS65988.
How does cable droop compensation work in the TPS25832AQWRHBRQ1?
The TPS25832AQWRHBRQ1 implements cable droop compensation by sensing load current via the CSP–CSN/OUT differential pair and linearly increasing the buck regulator's output voltage (VBUS) to offset IR drop across the USB cable. Using the IMON resistor, designers set the compensation slope-e.g., 1.0 V at full 3.5-A load-ensuring the measured VBUS at the connected device remains near 5.1 V regardless of cable length or gauge.
What protection features are excluded in the TPS25832AQWRHBRQ1 compared to the TPS25830A-Q1?
The TPS25832AQWRHBRQ1 excludes short-to-VBAT protection on the CC1, CC2, DP_IN, and DM_IN pins-unlike the TPS25830A-Q1, which supports up to 18-V short-to-battery tolerance on those lines. All other protections-including VBUS short-to-VBAT, DP/DM/CC short-to-VBUS, IEC 61000-4-2 ESD, overvoltage, overcurrent, and thermal shutdown-are retained in both devices.
Can the TPS25832AQWRHBRQ1 be synchronized to an external clock source?
Yes, the TPS25832AQWRHBRQ1 supports frequency synchronization via the RT/SYNC pin. When pulled above the internal PLL upper threshold (~3.5 V), the pin transitions from resistor-programmed mode to a high-impedance clock input. An external clock signal (300 kHz–2.2 MHz) can then synchronize the buck regulator's switching frequency, reducing EMI peaks and enabling deterministic timing in multi-rail automotive systems.
